To all whom it may concern: 7 i Be it known that I, ()TISB. ANGELL, a citizen of the United States, residingat 'H'averhill, in the county of Essex and State of Massachusetts, have invented certain new and-useful Improvementsin Machines for Setting Edges, of which'the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for setting and burnishing the edges ofshoe soles and more particularly to means for sup- 1 porting and for reciprocating the operat- [out in the claims. 1 .7

essential elements relating to'the tool-op- ,in working positionat the'will of the opproved combination of parts will be hereining tool. I 1 g a In machines of the above. type as at present constructed and 111 which cranks or eccentrics have been employed'for reciproeating the tools, much annoyance hasbeen caused by reason of the excessivevibration produced, resulting in disagreeable noise and rapid wear of parts. Itis an object of the present invention to so construct a machine of the above type as to eliminate all .unnecessary machine partsand at the same time to reduce undeslrable vibration to. a

minimum.

It is a further object of the invention to providein an edge setting machine a tool holder constructed to simultaneously hold a plurality of tools and adapted to be so controlled as to present either of said tools erator.

Other and additional objects and advantages of the present invention together with desirable details of construction and imafter described and particularly-pointed Figure 1 isa side elevation showing the erating mechanism, certain parts being i broken-away to show the internal structure-- Fin. 2 is an end elevation-of the same, with parts broken away. Fig. 3 is a top plan view and Fig. lisa 'dlagrammatlc eleva- -"tional view illustrating the operativemechanism as mounted in. posit on on the ma-.

chine frame.

-1 indicates a hollow Shaft which may be suitably supported in bearings upon the frame of the machine, suitable means being provided as herein shown for continuously rotating said shaft. Such means maycomprise'a pulley 1 and a driving belt, or any I MACHINE non snr'rme nnons.

sof thei known [equivalents therefor. d/Ylthlllfiflidfl IOHOW shaft 1 islocated a relat vely fixed shaft, support,;or rod 2. Any

. desirable means as herein illustrated may be provided for holding said shaft'in either of two positions, 180 degrees apart, andifor turningsaid shaft from one of said: posi tions to the other. This means may comprisea gear 3* fixed to the shaft 2, and suit able devices for turning and locking said gear, such. devices as herein shown for example c mprisinga rack segment fast ona shaft 5 0 andmeshing with the gear 3" and a locking and turning handlelever fastto the other end: of the shaft,butgno, claims are made herein to this part ofthe mechanism, and any other equivalent means may be siibstitutedtherefor. 7 i i The outer end of the supporting shaft is provided. with anenlargement l,'said enlargement being slotted or bifurcated; to.

form two opposed spaced apart arms 5 and 6. Passing through Valined'bearing open- .ings in said armsis a pintlepin or shaft 7, said shaft being provided upon one end with-a head; 8 and being screw-threaded" upon'the-other end at 9 to engage "with the screw threads of a nut 60. Mounted to rock about saidpin 7 between the arms. 5 and 6, and in the-vertical planeof the shaft 1, is a tool-carryingheadlO, said head being protending portions 11 .andf12, theextremities of said portions 111' and 12 being provided with members 13 and 14 adaptedto have Thehead 10 's' slotted in its central plane,

as shown at 15,{said slotted portionextending into the parts 11 and 12. respectively.

. vided with. upwardly and downwardly, ex-

. mounted thereo thev u l 7 to 01 h 01 ders l "p oyed in this typeof machine," 7

Withinthe extremities of the slot in said I head are mountedapair-of rollers 16 and 17, said rollers being .mounted to. turn in said slotby means of pins 18 and l9-passing throughthe side portionsof the head, and

secured therein in any suitable manner.

The rollers 16' and 17, as wilLbe noted by inspection ofv Figs, 2 and-.3, are provided. with central grooves 20,";the purpose of which will be hereinafter noted. 7

-As shown at 21 the shaft l-is provided at its end with a cam or eccentric pin and en-f gaging said. pin or cam by means of a suitable journal opening is a block 22, .said block being grooved at'its upper. and lower edgesas shown at 23. 24 is ayoke-member I having a central opening '25. encircling the shaft 1, said yoke-memben however, ing free to move both up and down and later.-

ally with respect to the shaft. The yoke 24: is provided with tongues 26 adapted to slide within thegrooves 23 of theb1ock 20,

- and is further provideduponthe outer-end of vitsarms with cam surfaces 27,28, said surfaces being arranged ifor contact with the rollers 16 and 17 respectively. p 7 Projecting centrally' of cam-members'27 and 28 are ,apair of-fins 29,30,"said fins being arrangedto project within the grooves of the rollers. Y

Thesoperation "of the machine is as fol lows: With thesupport 2 heldin fixed'position, the head 10 being thereby-retained in'a vertical plane, rotationof'shaft 1 will cause rotation of the cam' or' pin2l fixed. thereto As said pin has'bearing engageenu with the journal :openingin block 22,

said 'bloc'k will beiforced to "assume a rotary movement with respectto a fixed point upon the frame' of "the machine. 1 As. the yoke-, member 24is in engagement withlsaid block, said yokemei'nber tends to" partake of the movement of'the block, but by reason of the construction :shown, however, including the slidable engagement of'said block and ,Y'Ok, the verticaljcomponents only of the mov ment of said'bloclfa re effective in movin' the yoke 24, horizontal components the 'yoke due to the horizontalslidin of ot such movementbeing of no efi'ect upon block within the yoke. As; the cam sur aces '27 and'28' are in contact. with the rollers 16 and 1 7, the 'vertical'movement of the yoke, through the cam actionof said parts, will cause thehead 10 to rock about its piv- 1' otal' sup ort 7, ;thus producing a desired action o the operatingtools. As}. will be 'notedfrom 'the"construotion described, the

' block and yoke would be free'toturnwith the shaft, and wouldtherefore' be ine'flfective except for thefprfovisionpf the finsenga'gina-W thin th sre ves; i-the rollers, *"rthe' roller'sare held'in a fixedyertic'al plane,

as above indicated it is the purpose of this 7 invention to employ said tools, alternatively as byturning'the supporting head2' in'to either of two diametrically o posed positions, it is within the scope 0 this invention to employ a single tool'holder upon fs'aid head' andto 'provide means to hold said herein disclosed, and as is customary in such machines, the tool holders are; arrangedin a substantially vertical plane','it may be noted that bymerely changing the fixed position of the shaft or support 2 the tools .might be located 'to operate inany-oth'er preferredposition, and such change'of op- ,erative position is. '.contemplated as. within the scope of the present invention.

mentfoff the invention, it is not to'beunderstood that it is to'be limited to the specific details hereinbefore described, but that any lVhile the aboveis a preferredxembodior all changes or modifications of structure withlnthe province of mechanical skill are to be regarded as a part'thereof so faras they may beembraced within the scope of the annexed claims. r
